Unusual Temperature‐Enhanced Bulk Photovoltaic Effect Beyond the Centrosymmetric Phase in CuCrP2S6 van der Waals Crystals

Advanced Functional Materials, EarlyView.
Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...

Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers

Advanced Functional Materials, EarlyView.
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals

Advanced Functional Materials, EarlyView.
Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.
